1 | # check_SIGINT
2 | Programs that check accidental SIGINT command. 
3 | 
4 | There might have a time when you had to copy a data from terminal but you forgot to press shift key
5 | while copying that caused an accidental SIGINT signal which generally causes lots of data loss and time loss
6 | 
7 | To prevent this you can add these codes in your program as a verification 
8 |

 1 | #!/bin/bash
 2 | # main
 3 | trap 'myExit;' SIGINT

 5 | myExit()
 6 | {
 7 | 	echo "Do you really want to exit? press y to confirm ...."
 8 | 	read answer
 9 | 	if [[ "$answer" == "y" ]]; 
10 | 		then
11 | 			echo "program is exiting...."
12 | 			sleep 1
13 | 			exit
14 | 		else
15 | 			echo "program will continue"
